WebGrabPlus - Must Run as PID=0 (root)

Have just installed the latest Container (first time for me).

However, running with PUID=1000 and PGID=1000 doesn’t work. I must set these to 0 (root) for it to work, otherwise the cron job fails.

[Critical] Object reference not set to an instance of an object. 
[Critical] at . ..ctor (System.String ) [0x01381] in <fbac90b70d384f53ad4ad19bec96974f>:0 at .―. (System.String[] ) [0x00351] in <fbac90b70d384f53ad4ad19bec96974f>:0

This seems to be a common issue that is being spoken about on all different forums.
